feat: socket syscalls (socket/bind/listen/accept/connect/send/recv/sendto/recvfrom)

Kernel socket subsystem over lwIP TCP/UDP PCBs with ring-buffer RX,
wait queues for blocking ops, and fd integration via sentinel file
structs (flags=0x534F434B).

Socket dispatch extracted to separate noinline function to prevent
syscall_handler stack overflow that caused heap corruption.
